Abstract

The images taken by digital camera can not only be filmed out or printed out colorfully but also shown on televisions and computers. In order to output a higher quality image, analyzing and researching of digital images by software and algorithm were given in this paper. For example, researching the resolution of digital images can provide the size for optimize the output picture, make the images size after computer processing had the same detail as the original one with higher sizes, the images after processing could gain higher magnification and clearer interface; researching the color of the images after computer processing could correct the color which was out of line, the output images could be more verisimilitude; researching the whole image through optimal processing at deficient parts could decrease the noises which caused by the digital camera system; analyzing objects of the images, such as edges, color and luminance changing, with interrelated algorithm of digital image processing could make the images super-resolution zooming more perfect, image cutting, image mosaic, print character of the images were also discussed.
